The linear actuator is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be seen as a rotary electric machine split in a radial direction and spread out into a plane. Linear actuator motors can be classified into three types: cylindrical, U-groove, and flat type linear motors. Tubular linear motors are a type of cylindrical motors. Tubular linear actuator motors are also called pen linear motors, which is a kind of miniature push rod lifting (retractable) motor with small power. The main transmission structure is assembled by a drive motor (motor), gearbox (reduction gear), nut, guide sleeve, inner tube, outer tube, slider, micro-control switch, etc. The parameters of the tubular linear motor used in different fields are also different. The parameters are usually customizable, such as gear transmission method, reduction ratio, output torque, output speed, power and vo...
